- Abstract
Broad sense heritability and selection responses were assessed for grain yield and related traits in 12 F3 populations of wheat got from mating of six advanced lines and two widely cultivated cultivars (Pirsabak-08 and Janbaz) at University of Agriculture, Peshawar during 2013-14. All wheat genotypes (8 parents and 12 F3 populations) showed significant differences for all traits. Cultivar Janbaz had maximum spike length (13.9 cm) and maximum number of grains spike-1 (89.2). Parental line B-IV(N)5 had maximum single spike weight (4.6 g), 100-grain weight (4.6 g) and grain yield (32.0 g plant-1). F3 population B-RF7 × Janbaz had 100-grain weight (4.5 g) and grain yield (31.9 g plant-1). Similarly, F3 population B-RF1 × Janbaz had more single spike weight (4.1 g). Population B-RF3 × Janbaz had maximum spike length (14.5 cm) and number of grains spike-1 (85.1). F3 populations B-RF7 × Pirsabak-08, B-IV(N)5 × Pirsabak-08, B-RF7 × Janbaz, B-IV(N)5 × Pirsabak-08, B-RF7 × Janbaz, B-RF1 × Janbaz, B-IV(N)12 × Janbaz had maximum heritability and selection responses for plant height (0.76 and 10.96 cm), spike length (0.93 and 4.51 cm), grains spike-1 (0.93 and 25.54), single spike weight (0.89 and 3.08 g), 100 grain weight (0.90 and 1.26 g) and grain yield plant-1 (0.75 and 12.15 g), respectively. On basis of high heritability coupled with high selection response for yield related traits, F3 populations B-IV(N)5 × Pirsabak-08, B-IV(N)5 × Janbaz, B-RF1 × Janbaz and B-RF7 × Janbaz should be advanced further for possible development of high yielding wheat cultivars.
